A- Proliferation of ECFC cultured in EGM-2/20% FBS, EGM-2/5% FBS and EBM- 2/1% FBS in the presence or in the absence of treprostinil, evaluated after 3 days by measuring cellular phosphatase activity.
B- Effect of treprostinil on ECFC proliferation in EGM-2/5% FBS in the presence or in the absence of Indomethacin evaluated after 3 days by measuring cellular phosphatase activity.
C- Effect of treprostinil on ECFCs proliferation in EGM-2/5% FBS in the presence or in the absence of a cox1 inhibitor SC-560 evaluated after 3 days by measuring cellular phosphatase activity.
D- The percentage of ECFC undergoing at least 1 cell division after 14 days of culture in the presence or in the absence of treprostinil. Results represent the mean ± SEM of 3 independent experiments using single endothelial cells derived from different donors.
E- Number of cell progeny derived from a single ECFC in an individual well after 14 days of culture. Results represent the mean ± SEM of 3 independent experiments.
F- Number of ECFC isolated from umbilical cord blood (CB). Results represent the mean ± SEM ECFC of 5 independent experiments for cord blood samples.
